If you can make it happen, I am only glad for it. I think it is a shame that so many people miss out on maths. I haven't tried to teach it yet, so I can't really say. I've tried at times to come up with real world applications for the maths taught at school, but didn't come up with much.

I think one exercise I would give my pupils would be to determine the real prices of mobile phones.

Enjoyed the shoelace link, will try it the next time I tie my shoes.
